Always inspect your electric water pump for leaks and unusual sounds, includes aluminum screws in packaging
The common failure signs for this new style electric water pump are coolant leaks and whining noises in the area from the water pump. Unlike a standard water pump that is belt driven, these never electric water pumps don't show symptoms of potential failure. We strongly suggest that you replace the water pump before a complete failure which may lead to an over heated and damaged motor.
Engine Water Pump
Your vehicles engine water pump is responsible for keeping coolant flowing through the engine. As water pumps get old the internal bearing can go bad causing noise and a coolant leak. A good indicator that your water pump is failing is if you see coolant leaking through the water pump "weep hole".
